[PATCH] Git.pm: Make _temp_cache use the repository directory

["Marten Svanfeldt (dev)" <developer@svanfeldt.com>]

Update the usage of File::Temp->tempfile to place the temporary files
within the repository directory instead of just letting Perl decide what
directory to use, given there is a repository specified when requesting
the temporary file.

This fixes issues when the Perl in use uses a different format for paths
than in use by native code in the git tools such as msysgit with msys-perl.
